PURPOSE/AIM

1. Review the various artifacts seen in ultrasound 2. Review the physics and causes of these artifacts. 3. Illustrate the various artifacts in phantoms and various organs. 4. Discuss the technique to recognize these artifacts and in some cases use them to a clinical advantage.  

CONTENT ORGANIZATION

1. Basic principle of linear propagation and reflection of ultrasound 2. Artifacts seen in ultrasound: reverberation, mirror image, ring down, comet tail, multipath reflection, range ambiquity, side and grating lobe, refraction, shadowing and enhancement, beam width, Doppler 3. Illustration and explanation in phantoms 4. Techniques to recognize and correct artifacts 5. Illustration of these artifacts in various organs and clinical situations 6. Recognition and reduction of artifacts

SUMMARY

1. Artifacts in ultrasound can be mistaken for pathology. It is impreative to avoid this pitfall. This presentation teaches the various artifacts seen in ultrasound with an understanding of the physics involved and techniques to recognize these artifacts. 2. Illustration of these various artifacts in phantoms and different organs is presented.
